We left this on the rock wall by the entry. There is a $3 entry fee to tour the grounds and inside the castle, but you don't have to pay it to access the book. The $3 is well worth the visit though.

If you are the finder of this book, welcome to the site. Please make a journal entry so that I know it has been picked up and found. To do so is free and you can do it anonymously. You can read the book or not, keep it, pass it on to someone else you think might enjoy it, or leave it in a public place like I did.
